DEVICE FOR LEVELENG AND ALiGNlNG SHAFTENG.

SPECIE'ICATiON forming part of Letters Patent No. 318,886,6lated May 26, 1885.

Application filed March 10, 1885. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES ESPENSOHIED, of Hastings, in the county of Dakota and State of Minnesota, have invented certain new and useful Improvements in Leveling and Aligning Shafts; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereomwhich form part of this speciiication.

Figure l. is a front elevation of my invention. Fig. 2 is a plan view showing the same in operation. Fig. 31s afront elevation showing the same in posit-ion for aligning.

The invention relates to improvements in mechanism adapted to ascertain the departure of shafting from level or alignment, its object being to provide means whereby such departure can be quickly and readily discovered; and it consists in the construction and combination of two or more similar shaft-clamping devices, hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings by letter, A represents a clamping device composed of the body-plate B, hinged or pivoted clamping-bar O, and clamping-screw D, as shown. The body-plate B is provided with the rectilinear edges B B, at right angles to each other, and respectively provided with the levels Z) I). The edge of the device opposite the edge B is cut away to form the arms E E, parallel to the edge B and to each other, and the rectilinear edges 13 F, which run at opposite angles of forty-five degrees with the edge 15, and form with each other the re entering rightangle f. approximating the edge 13*. The arms E E and edges F 13 form between thcin the recess Z.

G is a centering-mark on the body-plate, which mark runs from the edge 13, at right angles thereto, to the angle f, in the line bisecting the said angle. The clamping-bar O is hinged or pivoted at one end,c, on the end of the arm E, or in a recess therein, and has its outer end passing intoa recess in the end of the arm E, where it is retaincchwhen necessary, by the pin a, which passes through proper openings in the ends of the bar and arm.

c is atra-nsverse threaded opening in the bar 0, which opening engages the clamping-screw D, which is provided on its outer end with a proper handle, (I, and on its inner end with a clamping-foot, d, to bear when the device is attached thereto.

H is a graduated glass tube secured to the body-plate perpendicularly to the edge B. The said. tube is open above and below, and has coupled to its lower end arubber tube, it. The tubes H and h. are for leveling purposes,as hereinafter explained, but form no part of the invention,as the leveling can be done by any of the ordinary methods. The edgeXof the bodyplate is parallel to the edge 13, and the screw D, opening 0*, anglef, and centering-mark G are midway between said edges. While this is not essentially necessary, itis better in practice.

To level a shaft one of the described devices is clamped thereon near each of its bearings, and the edges B B of all brought horizontal by the levels I) I). The said edges are then all vertically equidistant from center of the shaft, and the necessary leveling, if any is required, can be given by using a straight-edge with a spirit-level attached and leveling from thetop edge of one device to that of the adjacent one. If obstructions intervene,the graduated glasses H H and tubes h 71, all running to the same source of water-supply, can be used. I The said glasses and tubes form part of my former application for patent.

In aligning, the devices are clamped on the shaft and the edges B" brought horizontal by the levels If. The centering-marks G G will then be vertically over the axis of the shaft, and the aligning can be done from a cord stretched between said marks, or between points equally above or to one side of the same, when obstructions intervene.

Having described my invention what I claim 1. In mechanism to discover the departure from level of shafting, a clamping device pro vided with a rectilinear edge having a level attached to bring ithorizontal, arecess,Z,having a right angle, f, the bisecting line of which is parallel to the rectilinear edge of the clamping device, and a clamping-screw adapted to bind the shaft against the edges F F of thereccss Z, with its axis in the same horizontal against the shaft Y I plane as the bisecting line of the anglef, substantially as specified.

2. In mechanism to discover the departure from alignment of shafting, a clamping device provided with arectilinearedgehavingalevel attached to bring it l10rizontal,arecess, Z, having a right angle, f, the bisecting line of which is perpendicular to the rectilinear edge of the device, a centering-mark made on the extension of the said bisectingline, and a clamping-screw adapted to bind the shaft against the edges F Fof the recess Z,with its axis passing through the vertical plane in which the centering-mark lies, substantially as specified.

3. In mechanism to ascertain the departure from level of shafting, the combination of two or more clamping devices, A, each composed of the body plate B, clamping bar 0, and

In testimony that I claim the foregoing as my 0 i own I affis: my signature in presence of two witnesses.
